Of relevance to hyperacusis, prior noise-induced hearing loss leads to the generation of prolonged and repetitive activity in type II neurons and surrounding tissues. This aberrant signaling may be the basis for the sensitivity to everyday sounds seen in hyperacusis.

Most of my life I had no ear problems. I never thought about the noise I was exposed to, certainly never in terms of the grave hazard and enormous threat that I now know it to be.
